Its interrupting capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 — the IEC 60947-2 figure is the one that governs industrial panel coordination where fault current may exceed residential limits.
The IP20 protection class (with connected conductors) means it belongs inside a panel or distribution board — not in a washdown or outdoor location.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The interrupting rating is 5 kA per IEC 60947-2, and 4.5 kA per EN 60898.
The part carries ratings per EN 60898 and IEC 60947-2, and is halogen-free and silicon-free. Standard Siemens declarations (CE, UKCA, RoHS, REACH) apply to the SENTRON series.
